To meditate is to observe, and there is no wrong way to observe.
When you meditate, your mind is either in a calm state, like the surface of a placid pond. Else, it is frequented by a variety of thoughts like ripples on the pond’s surface.
If you observe how calm your mind is, you are meditating correctly. If you observe how your mind is filled with thoughts, you are also meditating correctly.
The only way to go ‘wrong’ here is to not observe. But then, if you are not observing, you are not meditating either.
